Summary of the invention
A kind of crushing juice rate that improves Rosa roxburghii, the Vc rate of transform that the objective of the invention is to overcome above-mentioned shortcoming and provide, mouthfeel is good easy to carry, long shelf-life, Vc and SOD stable content, Processes and apparatus are simple, and efficient is high, the Rosa roxburghii solid beverage of less energy consumption.
Another object of the present invention also is to provide the preparation method of this Rosa roxburghii solid beverage.
Rosa roxburghii solid beverage of the present invention is made by following proportion raw material: Rosa roxburghii Normal juice: 10~20L;
Sweetener: acesulfame potassium 0~20g, white granulated sugar 0~6kg, xylitol 0~6kg, isomalt 0~6kg;
Filler: maltodextrin 0~4kg, soluble starch 0~4kg, water-soluble dietary fiber 0~4kg.
A kind of preparation method of Rosa roxburghii solid beverage may further comprise the steps:
(1) refrigerated centrifuge is got juice: with the screening of Rosa roxburghii fresh fruit, after the cleaning, descended freezing 6~48 hours at-5~-50 ℃; Thaw under 15~60 ℃, put into rotating speed and be 2000~8000 rev/mins centrifuge and centrifugalize and get juice;
(2) allotment: sweetener, filler are slowly added in the Rosa roxburghii Normal juice, and the limit edged stirs, and until abundant dissolving, filters;
(3) drying: filtrate filtered, EAT are 130~210 ℃, spray-drying under 55~100 ℃ of conditions of leaving air temp.
(4) moulding: process pulvis or granule.
The preparation method of above-mentioned Rosa roxburghii solid beverage, wherein: thaw for thaw naturally, water drenches to thaw or to heat and thaws.
The preparation method of above-mentioned Rosa roxburghii solid beverage, wherein: filter and adopt the order number to be 80-300 purpose sieve or spun silk cloth.
Can know that from above technical scheme the present invention compared with prior art has following tangible advantage:
The Rosa roxburghii fresh fruit is put under-5~-50 ℃ the condition, and surperficial position freezes earlier, and centre moisture outwards moves; Form uneven needle-like ice crystal, thereby burst cell membrane, Rosa roxburghii fresh fruit tissue has become spongy after waiting to thaw; Thereby it is more complete to make that Rosa roxburghii tissue fluid discharges; Overwhelming majority nutritional labeling has got in the juice, and crushing juice rate reaches 60%~70%, and the crushing juice rate of existing broken juice technology generally is 30%~40%.Both compare, and refrigerated centrifuge is got the crushing juice rate that juice has improved Rosa roxburghii greatly.Freezingly combine with centrifuging and taking juice, compare with existing broken juice technology, the Rosa roxburghii Normal juice that obtains is clarification, and the concentration that concentration adds the water making beating is high, can directly omit clarification and concentration technology process aborning.This technique process and equipment are simple, and efficient is high, and less energy consumption has reduced production cost, is suitable for suitability for industrialized production.Spray-dired drying time is short, reduces the refining losses of Vc, and the amount that the Vc in the Rosa roxburghii Normal juice effectively transfers in the instant powder of dry spraying can be up to 94%.
